To obtain a permit to have an on-site sewage system installed, a soil profile analysis and plan review must be done. Soil Profile AnalysisA soil profile analysis is performed by an environmental health specialist on each lot prior to the design and construction of a private sewage treatment system. The purpose of the analysis is to determine the suitability of the soil for absorption and treatment of the effluent. The soil is analyzed to a depth of five feet. The properties of the soil, such as texture and structure, are determined as well as the depth of ground water, seasonal water table or bedrock.
A completed application, along with the fee (see fee schedule), must be submitted by the lot owner or authorized representative before the analysis can be scheduled. The applicant should provide a plot plan prepared by a qualified professional, such as a registered land surveyor, showing the lot boundaries and placement of the house and other structures. The applicant is also responsible for hiring a backhoe operator who will schedule the time of the analysis with the Johnson County Environmental Department (JCED) and meet the environmental health specialist at the site. It is recommended that the homeowner and/or builder attend the meeting on site. The backhoe operator will dig as many pits as necessary, in appropriate locations, in order to find the best soil conditions on the existing lot. Soil samples are obtained from the pits for analysis and future reference, and the pits are backfilled by the backhoe operator. The applicant will receive a letter containing the results of the analysis and stating the type of private sewage treatment system that can be permitted for that particular lot.
Plan ReviewWhen making application for a private sewage treatment system installation permit, the following materials must be submitted for review:
The design plan for the private sewage treatment system must be prepared by the installer or designer licensed by JCED or a licensed engineer. The design plan shall be drawn to scale, no greater than one inch equal to fifty feet (1" = 50'), and shall include, but not be limited to, the following information:
The plan review will be conducted by the environmental health specialist who performed the soil analysis and the site evaluation. The time required for the plan review will vary according to the type of sewage treatment system that has been designed. Most plan reviews can be completed within five days.
Permit for InstallationThe permit to install a private sewage treatment system is issued after the plan review has been completed. The permit is approved by the Sanitation Division Director of JCED prior to issuance to the homeowner or authorized representative. The permit will contain the site address and specifications regarding the size and installation requirements for the private sewage treatment system. Additional specifications and requirements for the installation of private sewage treatment systems are included in the Johnson County Environmental Sanitary Code. The permit applicant will be contacted when the permit is ready. A permit fee must be
paid at the time the permit is issued. House plans that were submitted for the plan review
will be returned, and the applicant will receive two copies of the permit, one to post and
one to submit to the appropriate building permitting agency. |
